2. The hinge as claimed in claim 1 , wherein the seat ( 10 ) has a plurality of threaded holes ( 11 ) defined through the upright arm.

3. The hinge as claimed in claim 1 , wherein the pintle ( 20 ) has a plurality of annular recesses ( 24 ) defined at the shaft ( 23 ).

4. The hinge as claimed in claim 3 , wherein the pintle ( 20 ) has a plurality of apertures ( 22 ) defined through the tongue ( 21 ).

5. The hinge as claimed in claim 1 , wherein the slot ( 14 ) has an inverted T-like shape.

6. The hinge as claimed in claim 1 , wherein the first arcuate lug ( 35 ) is protruded from a side of the first tab ( 34 ) opposed to the first channel and scalloped at a side of the first tab ( 34 ) facing the first channel; and the second arcuate ( 55 ) is scalloped at a side of the second tab ( 54 ) facing the second channel and protruded from a side of the second tab ( 54 ) opposed to the second channel.
